ManagedConversation references in ServletConversationManager not serializable

Deploying a CDI-enabled JSF application (with conversation scoped beans) with availability-enabled=true (to enable HTTP session replication) in latest GlassFish 3.1 cluster, and using the application results in the following error while persisting the HTTP session.

On further debugging, it appears that ServletConversationManager has a reference to ManagedConversations which are non-serializable and appears to be a regression (ie introduced after WELD-214).
